LAMP.

Specification of Letters Patent.

Patented Mar. 5, 1912.

Application led October 17,1911. Serial No. 655,190.

` been our purpose to make such a device of neat and attractive appearance and one which will more perfectly and uniformly diffuse the rays of light from the lamp.

Another object is to selectively control the color of the rays emitted by the lamp.

The novel features of the invention will-be apparent from the following description taken in connection with the drawings.

In the drawings, Figure 1 shows a side view partly in section of a lamp embodying our invention; and Fig. 2 is a perspective view of some'of the parts of our device.

As will be seen by reference to Fig. 1 We make use of a base pedestal '1 which maybe of any desired ornamental form, and it will be understood that the electric wires for supplying current to the lamp enter in the usual way at 2. At the top of the pedestal 1 there is anordinary socket for an electric incandescent light and-surrounding this socket, a part of the upper end of the pedestal, there is a holder 3 which may be made of ornamental form. Its lower end 4 lits on and is secured tothe pedestal while its upper end 5 is made ring-like with an interior supports ing tiange. Screws 6 pass through the said holder near its upper edge for the purpose of engaging a bead 7 at the bottom of the bell-shaped dome 8. The holder 3 may give an ornamental appearance and it will conceal from view the socket of the incandescent lamp or other light producing means. The dome 8 is made of glass and is in the shape ofan inverted bell which may be hemispherical as shown. Itvmay be made of )risinatic glass or vany other translucent orm which permits light to pass through it. A framev 9 having a circular base 10 with a depending end flange fits on the upper circular ,rim 11 of the dome 8 and the flange litting down in this dome securely holds the framein position. The frame has at its top a plate 12 provided with a central projection -13 extending upwardly and there is a'central hole through this projection and plate. The shade 14, in the shape of a dome, which may be made of cut glass or other ornamental material, tits over the plate 12 and has a central opening 15 through which the projection 13 extends, A clamping plate or meniber 16 fits down 011 top of the projection 13 and extends out over a portion of the shade to clamp it in position, and this plate has a screw -threaded stem 17 extending down throughl the opening in the projection 13 where it is engaged by a nut 18 to hold it in position.

It will be observed that by the above construction thel incandescent lamp 19 is surshade. rIhe frame which supports the shade rests on top ofthe glass vbell-shaped dome and is out of view, not interfering in any .way with the transmission of the light to the points where it is desired to be used.l

In the bottom part'of the column or pedestal 1 there is mounted a device 20 for se lectivelycon'trolling the color of the rays emitted by the light source. This device is in the shape of an arm which moves in the slot 21 to different positions and in moving it regulates the resistance in the circuit leading to the lamp, and we have found that this results in changing the color effect of the light.

Having thus described oui` invention what we claim and desire to secure by Letters Patent is:

1. In a lamp, the combination with a base, of a translucent inverted bell-shaped dome thereon adapted to contain a light, and a shade supported from and vsurrounding the upper edge of said dome.

2. In a device ofthe class described, the combination with a pedestal adapted to carry a lighting element at its top, of atranslucent bell-shaped dome secured thereto surrounding said lighting element and extending upwardly from said pedestal,

and a shade carried by and surrounding said bell-shaped dome and spaced therefrom.

.3. In a device of t-he class described, the

combination with a pedestal, of light producing means carried on the upper end of said pedestal, a shade, andmeans extending upwardly from said pedestal around said light producing means for supporting said shade, the lower edge of theshade surrounding the supporting means, the said supporting means being translucent whereby the light will be uniformly diffused.

4. In a device of the class described, the combination with a pedestal, of light producing means carried on the upper end of said pedestal, a shade, an inverted translucent bell-shaped dome secured to the top of said pedestal and extending up around said light producing means, and means independent of the dome for supporting said shade from the upper edge .of said bellshaped dome. i

5. In a dome of the class described, the combination with a pedestal adapted to carry a lighting element at its top, of a hemispherical transparent dome secured to the upper end of said pedestal and extending upwardly around said lighting element, a frame resting. upon the upper edge of said dome, and a shade carried by said frame and surrounding the same.

6. In a dome ofthe class described, the combination with a pedestal adapted to car a lighting element at its top, of a hemlspherical transparent dome secured to the upper end of said pedestal and extending upwardly around said lighting element, a' frame having a ring-like base resting upon the upper edge of said transparent dome, a shade adapted to lit over said frame, and means at the top of said frame Jfor clamping and securing saidshade thereon. f 7. In a device of the class described, the combination with a pedestal adapted to carry a light-ing element at its-top, of a prismatic hemisphere secured to said pedestal surrounding said lighting element, a frame mounted on said hemisphere, and a dome secured on said frame and depending therefrom around said hemisphere.

8. In adevice of the class described, the combination with a pedestal, of a lamp socket at its top, a holder surrounding said socket forming a part o said pedestal, a translucent' hemis here secured in said holder and extending upwardly therefrom, a frame having aring-like base resting on the top of said hemisphere and having a central upwardly extending projection at the top, a dome having a central opening fitting on said projection, and a clamping member secured to said projection and extending over a Aportion of the dome to clamp it i-n place.

In testimony whereof we aix our signatures in presence of two witnesses.
